Penn State researchers developing methods to prolong operating life of valve regulated lead-acid batteries; electric locomotive as example

Green Car Congress

A team of Penn State researchers is developing more cost-effective ways to prolong the life of valve regulated lead-acid (VRLA) batteries, such as those applied in Norfolk Southern Railway No. In this paper, the cell voltage and pressure of new and dead VRLA batteries are monitored during testing to determine the cause of death of the cells.

Axion Power and ePower Engine Systems enter 5-year agreement for use of PbC batteries in diesel-electric drivetrains for Class 8 trucks; tests suggest up to 35% improvement in fuel economy

Green Car Congress

We have worked with several types of batteries, including advanced lead-acid batteries, and have come to the firm conclusion that even VRLA or glass-mat batteries are not capable of sustained performance in this demanding application for over-the-road transport. Generator power is supplemented with battery under increased load—e.g.,
